. To all whom it may concern:

citizen of the United States, residing at Dayton, in the county of Montgomery and-State of Ohio, have invented certain new and useful Improvements in Cash Registers, of which declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers, and'has more'particular relation to improvements in registers of the type specifically-described with reference to the drawings which accompany and "form part of this specification.

Of said drawings; Figure 1 represents a rear elevation partly broken away of the upper portion of the machine of the type mentioned; the cabinet or inclosing casing being omitted. Fig. 2 represents a transverse 'vertical section through'a machine of the type mentioned with my improvements applied thereto; the cash drawer being omitted. Fig. 3 represents an end elevation of the ma. chine of the class mentioned, illustrating the tape printing mechanism. F ig. 4 represents. a vertical section partly broken away of one of the key banks and cooperating parts. F ig. 5 represents a detail rear elevation of the cross shafting and gears. Fig. 6 represents a detail rear elevation of the mainclutch. Fig. 7 represents a detail section,

I partly in side elevation, through one of'the counteroperating gears and its connections. Fig. 8 represents a detail top plan View otthe counter. I

As numerous parts shownin the present illustrations are also shown and fully described in the aforesaid British patent, attention is directed to this patent fors'uch detail description of the parts and their operation as is not hereinalter given. Described 1n 7 2. a that the keys. 1, which are-of the usual-springgeneral' terms, however, the machine may be said to comprise a series of banks of keys .1 representing amounts, a special group'.or' keys 2 representing clerks, and. three special keys 3, 4 and 5 representing respectively Paid out, Received on ,account" 'and' Charge? transactions. It is wvith these three'latter keys andtheir relation 'to-the mechanism of the machine that- .one offthe principal features of this invention has to'ido. The action of the amount keys 1 in connection] with the registering, indicating.- "and; printing mechanism best illustrated in Fig.

M the f or counter comprises a series of numbered wheels mounted upon a shaft 26, and each of the same provided with a ratchet wheel 27 fast to a sleeve 28 carried by the'said wheel 25. Located on the shaft 26 adjacent each of the ratchet wheels 27 is a mutilated-gear 28 carrying spring pressed pawl 29 which engages the teeth of its respective ratchet 27.

Each of the mutilated gears 28 meshes with a large gear 29 mounted upon the shaft 1.5, and each. of these gears in turn meshes with aoinion'ilil carried by a collar 31, (see Fig. 5.

and. held. in position by a collar 33 on its shaft. Adjacent each of the ms 3%)- is a corresponding pinion 34' tight v Matt 22.

will be seen from the above that each of lhitft-S 22, excepting that which connects the two special clerks indicators, is provided withapair" of pinions and 34; the first being loose on the shaft and connected to the registering gear, while the latter is fast on the shaft. ,During the normal operation of the machine each pair of these gears 30 and 34 is connected to move together by a inion 35 mounted upon a short arm 36, which is fast t one of a series oi rock shafts 37 extending =oss the machine, as best-shown in Fig. 7. rty this mechanism any motion transmitted by. the shafts 22 will be communicated through the pinions 34 and 35 to the pinions 30, and from them through the gears 29 to the counter wl'ieels; the pawls 29 riding idly over the ratchets 27 upon the backward frame.

movement of the gears. The object of the connecting pinions 35, carried by arms 36, is to provide means whereby, when desired, the counter operating gears may be thrown out of action'while still permitting the indicating and 'rinting mechanisms to perform their usua functions. To accomplish this result the shafts 37 are provided near their left hand ends, with mutilated pinions 38, which mesh with a rack se ment 39 journaled on the shaft 15 and norma ly drawn backward by a coilspring 40 which connects it to the-main The se ment 39is formed with rack teeth 41, which mesh with corresponding teeth 42 formed upon a segment 43, which is ivoted upon the shaft 8 and formed with a arm 44 and rock the same against the tenloosely mounted upon its respective sion of spring This will evidently rock the segments 39 so as to rotate the mutilated pinions 38. These pinions as before stated are fast on the shafts 37 which control the pinions 35 are immediately rocked out of em gagement withtheinions 30 and '34. It will be seen from this construetionv that the counter is normally connected for operation or in other words that the connections are normally effective. the bank (shown in Fig. 2) are depressed, these keys being used for certain special transactions, connections will then be disabled so that the counter will not beoperated at the )articular operation of the machine.

The coking devlees which are a part of this present invention are best shown in Fig. 7 but some of the operating devices therefor are shown in Figs. 2 and 4. Referring to Fig. 2 it will be seen that the gears 14 are n0rmally locked by pawls 51, these paWls being rigid with shaft 8. These pawls 51 are also shown in Fig. 4. On this figure is als shown arm 52 serving to lock a main segment 53 carried loosely by the main shaft 12. The arm 52 is also provided with a curved arm 54 the forwardend of which passes through a hole in a release key 55. The segment 53 56 and pinion 55 are also shown in Fig. 6

When the lower keys in audit will be seen from this'figure thatthe shaft 56 carries a pin 57 projecting in a slot58 of one member 59 of a clutch, the other mem ber 60 being connected to the pinion 55*" by a sleeve surrounding shaft 56. The shaft 56 is adapted to be given acomplete rotation at each operation of the machine for the purpose of releasing'the drawer latch, sounding an alarm and releasing the platen.= The machine is adapted to be operated'by a handle carried rigidly on shaft 12 and alsocarried by this shaftis a frame com rising arms 61 which are connected by a 1'0 62', these parts being shown in normal position in Fig.2. The pinion 55 has connected to it or to its carrying sleeve a spring 63 adapted to give the shaft 56 its rotation as before stated. When the special key 55 is depressed arm 54 is rocked thereby releasing arm 52 from the main segment 53, or rather, the arm is raised nearly above the periphery of the segment 53 sothat the cam portion of said segment, indicated by numeral 64 may, c0mplete the elevation of the arm 52 and thereby shaft 56 a complete rotation through the clutch 59-60 and causing a partial rotation of segment 53. lVhen the main handle is escillated in a direction which in Fig. 4 would be clockwise the rod or-bar 62 will strike a spoke edge 68 of the segment 53 and return the -dde's 'notrev'e'rsely rotate shaft 56 as will Y be'ciear fro'm thetypeof clutch used; It-

will be evident from the preceding description that shaft 56 is given a complete rotation. at ea'ch; operation of the special key but is not turned when handle is operated;

Referring now to Fig. 7 the shaft 56 is sifown this figureas carrying a cam 71. A second shaft 72' which may be termed the transfer contre'liin shaft isadapted to be given" an oscillation} to an extent equal to lllloffflafco "ple'te rotation in each direction ateaeh'operat on ofthe handle. This movemantis caused throughthe agency of a pinion mounted on this'shaft meshing with a gear caiiie'drigidly by shaft 12. 7 These parts are notshown inthepresent'drawings in as much as thya're-foundin the patented machine. I p'rovide a plurality of'lo-c'king pawls 81 for thbmntilated areas;

- retaining paw s during the forward movesensor the saidear and when the pin 13 is moved 'intocorita'ctf with the depressed key the-said gearis locke'cljagain's't movement in eitherdirection being' unable to'move for win-(11y bec'a'us'eof the key and being equally miaule'tbmeve rearwardl because of the ofis normally nearly in contact with the tails Gf'the'pawlsSLthe contacting edges being se shaped thatan oscillation of sleeve82 will "ca-rirthe tailsof'pa'wls 81 outwardly thereby withdrawingthe points of the pawls from the gears 28 and maintaining them out of locking position until the transfer shaft has resumed its normal position and the entire mechanism has been reset.

With the" construction as thus far described it wouldbe possible to slightly start tire-main handle thereby moving the sleeve 82 enoughto withdraw pawls 81 from the gears 28 and then to manipulate the machine" by manually operating the printing segments'25 shown in Fig. 3; To prevent this I rovide a series of detent pawls 84 also carried pawls 81, these paw'l's 84 being adapted to engage the teeth of gears 29. As shown in Fig. 7' the pawls 84 have depending teeth 86 adapted to be" normally engaged by the sleeve 82 and depressed against the tension ofv springs- 87 from the teeth of gears 29. When. the sleeve 82 begins to rotate or in other words'when the handle is started the pa-wls 84 immediately rise into contact with the teeth of gear 29?, thereby preventing any forward motion of the same so that the ma- These pawls act as loosely on the rod 85 supporting.

nipulation abovere'ferred to is prevented as nothing except a rearward motion could be case be given by the operating handle. I

It'is desirable to lock the gears 28 except when -it is desiredto operate them-and to this end I provide means for positively lockin 'the pawls 81. -'Th is means comprises a rod 91 carried by arm 92 of a-frame loosely carriedby the transfershaft 72. 'The arms 92 have a depending arm 93 connected through a pin 94-to a'link 95 carrying at its rear end gage/d by the cam 71. This link is supported by the arm 93: and by thelsha'ft 56'. It'will be clear that the 'pa'wls 81 must be unlocked when the diderential mechanism moves forward until stopped by the key and must also be unlocked when the parts are tobe' reset. The first of these objects is attained when shaft 56 begins to rotate in'as much as'the first movement'thereof carries the cam 71 away from the anti-friction roller 96 when a thereby rocking the frame'92 and carrying a rod 91 above the pro'ecting tails 98 of the pawls 81. It will be cl ear that then the gears 28 may be moved forwardly as the pawls 81 must be again withdrawn from locking position and this is accomplished by the transfer cams 101 which are adapted to strike the upturned end 102 of the link 95 and rock the same around the pin 94 which then acts as a pivot. Such rocking of link 95 will raise the anti-frictionroller 96 above the cam '71 when the spring 97 will immediately pull the link 95 forwardly as was the case when the cam 71 moved away from the roller 96. It will be clear that this will again release pawls 81 so that the sleeve 82 may remove them entirely from the path of the teeth ofgears 28.

In machines of the type shown in the present drawings and which depend for their operation upon the movement of the parts by springs it is possible when some of these parts project externally of the cabinet (such as the printer segments) to grasp such parts and hold the mechanism against operation in its proper time, thus causing the machine to print one amount and add another. By manipulation of the printing segments the machine might also be pumped to add a number 'ments, however, the parts are so looked that this manipulation is impossible and should the printing segments be once arrested by hand they cannot be again moved before the next operation of the machine. 9

It will be seen from the preceding description that the objects referred to inthe begi ning of the specification are well carried-out by the mechanism as described. 'When a of successive amounts which are not printed or indicated. With the present improvegiven a printing segment and this will in any an anti-friction roller 96 adapted to "be enspring 9;? will pull the link- 95. forwardly at this time act merely as detent pawls'. .When the parts are to be restored the rod 91 special transaction is to be entered in the machine the depression of the proper'key' 8, 4 or 5 will withdraw the inions 35 from their normal effective-position as connecting devices so that a subsequent operation of the machine will produce no e'lfectupon the register. The release of the de ressed special key however allows the mac anism to IGSUIILG iiJS normal position so that the counter again becomesoperative. ter controlling gears 28 are normally locked but are released when the shaft 56 is moved under the tension of spring 63 and are also sition lockin the ears 29 against forward movement.
